d. For multiple installations, the requirements for individual appliances
should be added together. Installation should be made in accordance with
local and national regulations applying at the time. A competent installer
must be employed.
e. The appliance flue discharges horizontally from the top of the unit. It
must not be directly connected to any flue, mechanical extraction system,
ducting, etc., which leads to the outside of the building. The appliance
is best discharged under an open canopy connected with a ventilating
system.
f. Install the unit with a minimum clearance to combustible and non-
combustible construction of six inches (152 mm) at the sides and six
inches (152 mm) between the draft diverter and the wall. Also leave
enough room for cleaning, maintenance, and service.
g. Electrically protective earth ground the unit at the terminal provided
(figure 1). This unit is fitted with an equipotential terminal in accordance
with national regulations and CE directives. Locate this marking for
equipotential terminal connection (figure 2).
2. Gas Supply
Incoming service must be of sufficient size to supply full rate without excessive
pressure drop. A gas meter is connected to the service pipe by the gas supplier.
Any existing meter should be checked by the supplier to ensure that the meter
has the capacity for passing the required rate of gas for the kettle in addition
to any other gas equipment installed.
The appliance governor is incorporated in the gas control valve which is
situated in the control cabinet. The control valve governor is suitable for both
natural and propane gases without conversion.
Installation pipework should be fitted in compliance with IEGE/UP/2. The
pipework should not be smaller than the gas inlet connection (Rp½ [½”
B.S.P.]). An isolating cock must be located close to the appliance to allow
shut-down during emergencies or service. Installation must be tested for gas
soundness and purged as specified in IGE/UP/1.
3. Electrical Supply
This unit is designed for connection to fixed wiring. A suitably rated isolating
switch with contact separation of at least three millimeters on both poles,
must be fitted to the installation. The wiring must be executed in accordance
with the regulations listed inside the cover page of this manual supplement.
Power supply to this unit must be 230V, 1 Phase, 50/60hz with wiring suitable
for an electronic load of 50 watts.
Cable entry is at the lower rear on right hand side of the appliance.
Access to the terminals is gained by removing access panel.
Electrical Safety & Advice Regarding Supplementary Electrical Protection
Commercial kitchens and foodservice areas are environments where electrical
appliances may be located close to liquids, or operate in and around damp
conditions, or where restricted movement for installation and service is evident.
The installation and periodic inspection of the appliance should only be
undertaken by a qualified, skilled and competent electrician; and connected
to the correct power supply suitable for load as stipulated by the appliance
data label.
The electrical installation and connections should meet the necessary
requirements to local electrical wiring regulations and electrical safety
guidelines. We recommend:
• Supplementary electrical protection with use of a residual current device
(RCD).
• Fixed wiring appliances incorporate a locally situated switch disconnector
to connect to, which is easily accessible for switching off and safe
isolation purposes. The switch disconnector must meet the specification
requirements of IEC 60947.

NOTE: With reference to the gas rate, pressure adjustments and conversions,
this appliance is CE-approved for use with the following gases:
a. Gas Category I2H, G20 natural gas may be supplied to the appliance in
Austria, Denmark, Finland, Greece, Iceland, Italy, Luxembourg, Norway,
Portugal, Spain, Sweden, Switzerland and the United Kingdom.
b. Gas Category I3P, G31 propane gas may be supplied to the appliance in
Germany, Ireland, the Netherlands, Portugal, Spain, Switzerland and the
United Kingdom.
Use of the appliance with non-approved gases in a listed country, or use in
other countries will void CE certification.
6. Burner Adjustment
The burner has a primary air adjustment. The gap should be 1/4” (6.35 mm) to
3/8” (9.53 mm).
